Sleep / Myth or fact?

Does warm milk with honey or linden tea help you sleep?

Not enough evidence. There is no strong study showing that warm milk with honey or linden tea makes you sleep. But there is no study showing that they do not work either. What we know is this: these drinks have been tested very little.

What we know

  • Milk: A systematic review (a study that brings together all the research on a topic) found 14 studies on milk and dairy products1. The results differed from study to study, and most studies were of low quality1.
  • Some building blocks in milk are thought to support sleep; but how much milk has how much effect is not known1.
  • Honey: Data on honey and sleep come mostly from children with a cough. Honey can ease a cough; after three days, there is no longer a difference in the effect of the cough on sleep4.
  • Linden: The European Medicines Agency recognises linden as a traditional herbal product for mild symptoms of stress. This recognition is based on a long history of use, not on clinical trials2.
  • A review of herbal products for insomnia found none of them better than a placebo (an inactive look-alike); linden was not among those studies5.

What we do not know

  • The effect on sleep in adults of a warm glass of milk alone before bed is not known1.
  • The effect of linden on sleep in humans is not known. A recent study was done only in mice6.

No evidence is not the same as not working. Here, lack of effect has not been shown; it simply has not been tested properly. A warm evening drink can be a ritual that helps you unwind. If it relaxes you, you can keep it up, knowing that it is a habit, not a medicine. If you have a baby, remember: honey is not given before the age of one3.

In depthmechanisms, studies, limitations

The PRISMA-based review by Komada and colleagues included 14 studies published between 1972 and 2019: 8 RCTs, 2 crossover trials, 1 longitudinal and 3 cross-sectional studies1. Of the 10 clinical studies, only 3 were rated as high quality; findings on drinking milk at night in older people were inconsistent1. The review was funded by a dairy industry association; although a tryptophan and alpha-lactalbumin mechanism has been proposed, a dose-response relationship has not been shown1.

The best data for honey come from a Cochrane review: in children with acute cough (6 RCTs, 899 children), honey probably reduces cough frequency compared with placebo; after three days there is no advantage over placebo or salbutamol in cough severity or in the effect of cough on child and parent sleep4. This is not evidence about sleep in healthy adults.

The EMA monograph on Tiliae flos lists mild symptoms of mental stress as its second indication and does not recommend use under 12 for this indication; the indication rests on traditional use alone2. In a meta-analysis pooling 14 RCTs of herbal medicines for insomnia (1602 participants), valerian, chamomile, kava and wuling did not beat placebo on any efficacy measure5. A Tilia tomentosa extract increased NREM sleep in mice; this cannot be generalised to humans6.
